摘　　要：Fe-Mn-Al-C系钢因其低密度和优异的力学性能,成为轻质、高强汽车用钢的发展方向。与常规Mn含量超20%的高锰钢相比,中锰轻质钢在成本控制和加工方面优势显著。基于国内外相关研究成果,深入分析并总结了不同合金元素以及析出相对Fe-Mn-Al-C低密度钢组织性能的影响,以及不同类型低密度钢的强化机制和拉伸性能。此外,结合淬火-配分工艺特点,提出采用淬火-配分工艺对中锰低密度钢进行处理,并对其应用前景作出了展望。The Fe-Mn-Al-C steel has become the development direction of lightweight and high strength steel for automotive applications due to its low density and excellent mechanical properties.Compared with high manganese steels with a conventional manganese content exceeding 20%,medium manganese lightweight steels have significant advantages in cost control and processing.Based on relevant research achievements at home and abroad,the effects of different alloying elements and precipitates on the microstructure and properties of the Fe-Mn-Al-C low-density steel,as well as the strengthening mechanisms and tensile properties of different types of low-density steels were deeply analyzed and summarized.In addition,based on the characteristics of Q&P process,it was proposed to use Q&P process to treat medium manganese low-density steel,and its application prospects were also discussed.
